I'll start with a short story.
There was recently a race, where the rain stops before the race starts and never returns, but it was still wet so people uses inters at the start.
League has two compound rule, so people are forced to use two different compounds. But everybody already has a stint of inters, so we can use another dry compound for the rest of the race, right?
But people get disqualified, because intermediate wet doesn't count as a compound.
-------------------------
I know, that this isn't a bug, but the way how 2-compound rule work in iGP (min. 2 different dry compounds unless there's rain in a race) is really confusing. Why only dry compounds? Why rule cancels only if there was a rain? It's not what you can figure out instantly when see "2-compound" rule on.
So, I want to suggest a rework for 2-compound rule to sound and work like this: "you need to use 2 different compounds unless you use Inter or Wet"
or "you need to use 2 different compounds or Inter or Wet", that's basically the same with different words.
